The James Rebarscope is the digital version of a classic rebar locator, rebar finder which enables the user to not only locate reinforcement bars but also determine rebar depth and the rebar size. The Rebarscope is also capable of locating both ferrous and non-ferrous metals in concrete and other non-metallic construction materials such as copper, aluminium, some stainless steels, wire, and more.
The eddy current sensor is specifically designed to react to the outer surface of the metal object. It is uninfluenced by small metal particles in the concrete, whether the concrete is fresh or hardened, wet, or dry. This sensor has also been designed with temperature compensation circuitry as well. The temperature compensation circuitry not only improves accuracy and performance but allows the operator to use the equipment without a "zero" procedure first. As always only one sensor is required for all depth ranges and functions of the equipment.
The latest in microprocessor technology not only conditions the signal from the sensor for more accurate and dependable results but provides the user with the information they need. Rebar diameter can be estimated by using a simple system of comparison. All this is fully automated for consistent, repeatable results with increased resolution over previous models.

30/11/18 - Typical limitations in seals have been overcome thanks to recent
developments in elastomers and the ability to make a two-part seal combining carbon
fibre reinforced plastic (CFRP) with a special low friction, high modulus
plastic as the sealing part.The CFRP component and the special plastic stabilise the seal geometry,
giving a previously unachievable, narrow contact surface between seal and rod
or barrel. This prevents the energised backup O-ring from increasing the seal
contact pressure, which can otherwise worsen friction and wear to seal, rod or
barrel. Thanks to these advancements, the development of long life actuators
with low friction, independent of load, and suitable for low amplitude high
frequency operation is now possible. However, to prevent loss of seal
lubrication the cyclic amplitude of movement must still be greater than seal
contact width. Since this type of seal
cannot be stretched or compressed, the seal must be slid into its groove and a
sleeve installed after to hold it in its groove. This type of actuator is still
cheaper than a hydrostatic bearing actuator without the leakage problems.Actuators with no seals and hydrostatic self-centring rod bearings have
almost zero friction, infinite life, high side load capability and no
limitation on cyclic amplitude of movement, and are, therefore, well suited for
precise control and low amplitude high frequency operation. However, there are two
primary drawbacks: they are expensive and they have high internal piston and rod
leakage. While external leakage can be prevented, the unavoidable internal
leakage reduces positioning accuracy and energy efficiency.Another limitation of hydraulic actuators – the weight of the piston
assembly, and also of the barrel – has been greatly reduced by the use of
carbon fibre reinforced plastic for these components. Reducing the piston mass reduces the effect
of oil compressibility and allows for higher frequency operation. Low barrel
mass is also required for high frequency multi-axis operation. All of these design features are included in the European actuators available
from Hylec Controls.

28/11/18 - Recent developments in elastomers and the ability to make a

part being a special low friction, high modulus plastic has overcome most of
the limitations of former seals. The CFRP component and the special plastic stabilises
the seal geometry, giving a previously unachievable, narrow contact surface
between seal and rod or barrel. This prevents the energised back up O ring from
increasing the seal contact pressure, which increases friction and wear to
seal, rod or barrel. Hence the development of long life actuators with low

two draw backs. Firstly they are expensive and secondly they have high internal
piston leakage and high rod leakage. Techniques are available to prevent
external leakage but the unavoidable internal leakage reduces positioning
accuracy and energy efficiency.Very recently another limitation of hydraulic actuators, the
weight of the piston assembly, and also of the barrel, has been greatly reduced
by the use of carbon fibre reinforced plastic for these components. Reducing the piston mass reduces the effect

19/11/18 - Hardness testing instruments have been in use for more than a century to
measure the strength of metallic materials and hardness of their surface
finish.The earlier models of these machines were bench mounted and measured
strength by applying a given force to a probe and making an indentation to cause
plastic deformation. The material hardness was determined by measuring the
depth or width of the indentation. However, different materials required different
shaped indenters and different methods of measuring the size of the indent. Additionally,
these machines were not suitable for fixed structures or very large or very
small and thin items, resulting in the development of less accurate portable instruments
using different methods of measurement. The two common methods for this application include the dynamic Leeb
method, used for large items, where a spring loaded probe impacts the surface
and its bounce back distance is measured; and the ultrasonic contact impedance method,
where different forces are used for different materials, as well as for small
items and for the thin surface finish on an item. Advances in digital technology have led to the development of an
instrument by a European manufacturer that not only offers extreme accuracy using
both Leeb and ultrasonic contact impedance methods but also tests to either US
or European standards. Key features and advantages of the new instrument include a camera to
record the position of the probe on the item and any identifying number on the
test item; digital readouts of hardness and statistics provided on the tests;
ability to detect and reject inaccurate Leeb readings; and facility to store all
the information from the tests in the instrument for downloading later to a PC.The accuracy and calibration of this instrument can be checked in the
same way as it’s done for bench testers by performing hardness tests on a range
of certified test blocks of known hardness.Available from Hylec Controls, the new portable
hardness testers equip users with greater capabilities, previously only
available on sophisticated bench mount testers, at a price similar to much
simpler portable instruments.
